Profit, P(2), is the difference between revenue, R(2), and cost, C(2), so P(x) = R() - C(3). Which expression represents P(x), if R(x) = 204 -32+ 2x - 1 and C(x) = 2* - 2? + 2.c + 3?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

thats not a system of equations, that is a solution
